You could probaly try to use templates and set a static port there, but dont forget to add them to the firewall aswell: Web domains and SSL Certicates — Hestia Control Panel documentation
For each port you would need a custom template.
If i understand correctly, then each domain with custom port should have different template, right?
If yes, then would it possible to add a custom port directly into existing web domain config instead of adding individual template? This would give more convenience to work, when Hesita - nginx acting as backend of multi sites.
Thanks so much.
Currently not, no - but there is already a feature request on github for it.
Got it, thanks @ScIT
I have just submitted the request.
